The processor may further send at least a first chunk of content data to the first device. The content data may be associated with the content. The processor may further receive a second request from a second device. The second request may be for the content. The processor may further send an identification of the first device to the second device. The processor may further send an instruction to the second device.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.

FIG. 1 illustrates an example system 100 that can be utilized to implement a hybrid content delivery system, arranged in accordance with at least some embodiments described herein. System 100 may be a hybrid content delivery system, which may be implemented with a content delivery domain 110. Content delivery domain 110 may store content data 120, which may be associated with content 124 such as a video. Content delivery domain 110 may be configured to deliver content 124, such as by distributing content 124, to one or more devices through a network 102, such as the Internet. As will be described in more detail below, during the delivery of content 124, devices 142, 152 may receive chunks of content data 120 from each other, or from other devices connected to network 102, or from content delivery domain 110. For example, device 152 may receive a first chunk of content data 120 from content delivery domain 110, and may receive a second chunk of content data 120 from device 142 during the delivery of content 124.

Content delivery domain 110 may include a processor 112 and/or a memory 114, configured to be in communication with each other. Memory 114 may be configured to store content data 120. Content data 120 may be divided, such as by processor 112, into one or more chunks 122, where each chunk 122 may include a same or a different amount of data. Each chunk 122 may correspond to a respective portion of content 124. For example, content 124 may be a video of a duration of twenty minutes. Each chunk 122 may correspond to twenty seconds of content 124, which may result in content data 120 including sixty chunks. Processor 112 may be configured to determine a duration of a corresponding portion of content 124 for each chunk 122, which may affect the amount of data in each chunk 122. Each chunk 122 may be delivered, by content delivery domain 110, individually among content delivery domain 110 and/or devices 142, 152.

In an example illustrated by timing diagram 128, content delivery domain 110 may start a distribution of content 124 at a start time 130. Content delivery domain 110 may distribution content 124 by distributing each chunk among chunks 122 sequentially over network 102. In the example, at a time between start time 130 and a time 131, a user 140 may wish to view content 124 with use of device 142. Device 142 may be a device such as a computer or cellular phone and may include a memory 144. User 140 may use device 142 to connect to network 102 and in response, device 142 may generate a request 146 for content 124. In some examples, user 140 may input a uniform resource locator (URL) in a browser application installed in device 142 to generate request 146. Device 142 may send a request 146 to content delivery domain 110 through network 102, where request 146 may be a request for content data 120. Device 142 may receive chunks of content data 120 which may be being distributed by content delivery domain 110 over network 102. In the example, request 146 may be a request to start viewing content 124 from a beginning of content 124. Processor 112, at time 131, may begin to send chunks 122 sequentially, starting with chunk 122 a, to device 142. Device 142 may continue to receive chunks 122 of content data 120 through network 102. In the example, in response to receiving chunks 122 a, 122 b, 122 c, device 142 may store chunks 122 a, 122 b, 122 c in memory 144. In some examples, if request 146 is a request to view the live broadcast of content 124, device 142 may first receive chunk 122 b, instead of chunk 122 a, from processor 112 starting at time 131.

In the example, at a time between time 131 and a time 132, a user 150 may wish to view content 124 with use of device 152. Device 152 may be a device such as a computer or cellular phone and may include a memory 154. User 150 may use device 152 to connect to network 102 and in response, generate a request 156 for content 124. In some examples, user 150 may input a uniform resource locator (URL) in a browser application installed in device 152 to generate request 156. Device 152 may send a request 156 to content delivery network 110 through network 102, where request 156 may be a request for content data 120. In the example, request 156 may be a request to start viewing content 124 from a beginning of content 124. Processor 112, at a time between time 132 and time 133, may begin to send chunks 122 sequentially, starting with chunk 122 a, to device 142. In some examples, if request 156 is a request to view the live broadcast of content 124, device 142 may first receive chunk 122 d from processor 112 starting at a time between time 132 and time 133.

Content delivery domain 110 may detect that more than one device is connected to network 102, such as by determining a presence of more than one request received at content delivery domain 110. In response to detecting more than one device are connected to network 102, content delivery domain 110 may send an identification 162 to device 142, and may send an identification 164 to device 152, at a time between time 132 and time 133. Identification 162 and identification 164 may each include identifications of one or more devices which are connected to network 102. In the example, identification 162 may include an identification of device 152, and identification 164 may include an identification of device 142. Device 152 may receive identification 162 and may determine (as illustrated by the question mark “?”) whether to establish a communication channel (described below) to request chunks 122 of content data 120 from device 142, or to continue to receive chunks from content delivery domain 110.

FIG. 2 illustrates the example system 100 of FIG. 1 with additional detail relating to an implementation of hybrid content delivery system, arranged in accordance with at least some embodiments described herein. FIG. 2 includes elements in FIG. 1, with additional details. Those elements in FIG. 2 that are labeled identically to elements of FIG. 1 will not be described again for the purposes of clarity.

Content delivery domain 110 may further include a module 230, which may be configured to be in communication with processor 112 and/or memory 114. In some examples, module 230 may be a component of processor 112. In some examples, module 230 may be an integrated circuit such as FPGA (Field Programmable Gate Array), SoC (System on a Chip), etc. Memory 114 may be further configured to store an instruction 216 and a database 236, where instruction 216 may be associated with establishment of a communication channel 270 among devices connected to network 102 (such as devices 142, 152). In some examples, memory 144 of device 142, and memory 154 or device 152, may be further configured to store instruction 216 prior to an implementation of system 100. Database 236 may include indications of devices which may be connected to network 102. In some examples, database 236 may further include indications of receiving times of requests, such as requests 146, 156, received from devices indicated by database 236. In some examples, database 236 may be stored in a memory different from memory 114. In some examples, module 230 may be further configured to instruct processor 112 to update database 236.

In the example, module 230 may receive request 146 from device 142 and in response, may analyze database 236 to generate identifications 162, 164. Module 230 may determine an absence of connected devices (to network 102) indicated by database 236 and in response, may instruct processor 112 to continue to send chunks 122 to device 142. In some examples, in response to the absence of connected devices (to network 102), module 230 may send a message to suggest device 142 to continue to retrieve chunks 122 from content delivery domain 110. Continuing with the example, module 230 may receive request 156 and in response, may analyze database 236 to generate and/or update identifications 162, 164. Database 236 may indicate that device 142 is currently connected to network 102 and is currently receiving chunks 122 from content delivery domain 110. Module 230 may update database 236, based on request 146, to indicate that device 152 is connected to network 102. Module 230 may generate identification 162 to include an identification of device 152 and in response, may send identification 162 to device 142. Identification 162 may be effective to indicate that there may be devices different from device 142 connected to network 102. Instruction 216, stored in memory 144, may be effective to indicate that device 142 may send requests to devices indicated by identification 162 for chunks 122. Similarly, module 230 may generate identification 164 to include an identification of device 142 and in response, may send identification 164 to device 142. Identification 164 may be effective to indicate that there may be devices different from device 152 connected to network 102. Instruction 216, stored in memory 154, may be effective to indicate that device 152 may send requests to devices indicated by identification 164, for chunks 122. Module 230 may further instruct processor 112 to send chunk 122 a to device 152. In some examples, module 230 may determine a difference between a first receiving time of request 146 and a second receiving time of request 156. If the difference between the receiving times is within a threshold, for example thirty seconds, then module 230 may include the identification of device 142 in identification 162. If the difference between the receiving times exceeds 30 seconds, module 230 may exclude the identification of device 142 from identification 162.

Device 142 may receive identification 162, and instruction 216, and in response, may store instruction 216 in memory 144. Similarly, devices 152 may receive identification 164, and instruction 216, and in response, may store instruction 216 in memory 154. In examples where instruction 216 may be stored in memory 144, 154 prior to the implementation of system 100, devices 142, 152 may receive identification 162, 164, respectively. In the example, in response to receipt of identification 164, device 152 may execute instruction 216, which may cause device 152 to send a channel request 250 to device 142. Channel request 250 may be a request to establish a communication channel 270 between device 152 and device 142. In some examples, communication channel 270 may be based on the WEBRTC (Web Real-Time Communication) protocol. Device 142 may receive channel request 250 and may analyze identification 162 received from module 230. Device 142 may determine that device 152 is identified by identification 162 and based on instruction 216 stored in memory 144, may facilitate establishment of communication channel 270 between device 152 and device 142. In response to the establishment of communication channel 270, device 142 may send device data 240 and progress data 242 to device 152.

Device data 240 may include information related to device 142 such as a location of device 142, a hardware profile of device 142, a performance of device 142, a quality value related to content 124, etc. The location of device 142 may indicate a particular city, town, state, province, etc. The hardware profile of device 142 may indicate models of processors, memory, network modules, etc., of device 142. The performance of device 142 may be related to processing speed, data transmission speed, available bandwidth, etc., of device 142. The quality value may be a resolution of content 124 such as whether content 124 is being display on device 142 in particular high definition video mode such as 720p, 1080p, etc. Progress data 242 may be effective to indicate a progress of display of content 124 on device 142. For example, progress 242 may indicate that when device 142 receives request 250, device 142 is displaying a fifty-third second of content 124. Progress data 242 may indicate “53 seconds”, which may be an indication that device 142 may be storing at least three chunks 122, where each chunk corresponds to twenty seconds of content 124. As will be described in more detail below, device 152 may determine whether to receive chunks 122 from device 152 based on device data 240 and/or progress data 242.

In some examples, device 152 may execute instruction 216 during a display of content 124 on device 142, and/or during a display of content 124 on device 152, in order to determine whether to request chunks 122 from device 142. In response to receiving device data 240 and/or progress data 242 from device 142, device 152 may analyze device data 240 and/or progress data 242. Device 152, based on the analysis of device data 240, may determine that device 142 is located in a same city as device 152. In response to the determination of the location of device 142, device 152 may determine to request chunks 122 from device 142. In some examples, device 152 may execute instruction 216 to sort IP (Internet Protocol) addresses of devices indicated by identification 164 or device data 240, and in response, identify devices of particular IP addresses, and request chunks 122 from the identified devices. In some examples, device 152 may collect device data 240 from device 142 over a period of time, and may determine to request chunks 122 from device 142 based on parameters such as a network throughput, latency, data transmission rate, etc., within the period of time. For example, device 152 may determine that an exchange of chunks 122 with device 142 within a past 10 minutes has a relatively low latency, and may determine to continue requesting chunks 122 from device 142.

Device 152 may analyze progress data 242 to determine a number of chunks 122 to request from device 142. In the example, in response to progress data 242 indicating storage of at least three chunks (122 a, 122 b, 22 c), device 152 may request at least one, or at most three, chunks 122 from device 142. Device 152 may send a chunk request 220 to device 142 through communication channel 270, where chunk request 220 may be a request for the determined number of chunks, such as one chunk (twenty seconds of content 124), i.e. chunk 122 b, from device 142. Device 142 may receive chunk request 220 and in response, may send chunk 122 b to device 152 through communication channel 270. Device 152 may continue to determine whether to request missing (chunks not stored in memory 154) chunks 122, such as chunk 122 c, from device 142, or to continue to receive chunks 122 from content delivery domain 110. In the example, device 152 may determine to receive chunk 122 c from content delivery domain 110. Device 152 may store chunks 122 a, 122 b, 122 c, in memory 154. In some examples, device 152 may flag chunk 122 b as a chunk which is received from a device instead of content delivery domain 110.

FIG. 3 illustrates the example system 100 of FIG. 1 with additional detail relating to monitoring of a hybrid content delivery system, arranged in accordance with at least some embodiments described herein. FIG. 3 includes elements in FIG. 1, with additional details. Those elements in FIG. 3 that are labeled identically to elements of FIG. 1 will not be described again for the purposes of clarity.

As will be described in more detail below, module 230 may be further configured to monitor system 100 based on traffic data 312. Each device connected to network 102, such as devices 142, 152, may generate respective traffic data 312. Traffic data 312 may include indications of an upload speed, a download speed, a number of devices connected, etc. As a result of the monitoring, module 230 may send an alert 320 to device 152, where alert 320 may indicate an undesirable performance of system 100. Device 152 may determine whether to continue to request chunks 122 from device 142 based on alert 320.

In the example, device 152 may generate traffic data 312 based on transmissions of chunks 122 between device 152 and device 142, or between device 152 and content delivery domain 110. For example, chunks 122 a, 122 b, 122 c, 122 d, may include 5,000 kilobytes, 3,500 kilobytes, 4,000 kilobytes, and 2,500 kilobytes, of data respectively. After device 152 received chunks 122 a from content delivery domain 110, device 152 may update traffic data 312 to indicate that a total of 5,000 kilobytes of data has been downloaded from content delivery domain 110. After device 152 received chunk 122 b from device 142, device 152 may update traffic data 312 to indicate that a total of 3,500 kilobytes of data has been downloaded from a device connected to network 102. After device 152 received chunks 122 c, 122 d from content delivery domain 110, device 152 may update traffic data 312 to indicate that a total of 11,500 (5,000+4,000+2,500) kilobytes of data has been downloaded from content delivery domain 110 through network 102.

In an example, device 152 may send traffic data 312 to content delivery domain 110 periodically. Module 230 may analyze traffic data 312 to monitor system 100, and may generate alert 320 based on the analysis. For example, traffic data 312 may indicate that device 152 is receiving chunks 122 from device 142 at a download speed of 3,000 kilobytes per second. Module 230 may compare the download speed indicated by traffic data 312 with a threshold speed, such as 5,000 kilobytes per second, which may be stored in memory 114. In response to traffic data 312 indicating a download speed lower than the stored threshold speed, module 230 may generate alert 320 to indicate that the download speed indicated by traffic data 312 is below the threshold download speed, and may send alert 320 to device 152. Device 152 may receive alert 320 and in response, may determine whether to continue to request chunks 122 from device 142 or to receive chunks from content delivery domain 110. In some examples, device 152 may be configured to execute instruction 216, stored in memory 154, to determine whether to continue to request chunks 122 from device 142 or to receive chunks from content delivery domain 110. In some examples, device 152 may receive instruction 216 from module 230, where instruction 216 may be further effective to instruct device 152 to analyze traffic data 312. Device 152, based on the analysis of traffic data 312, may determine whether to establish communication channel 270 with device 142 in order to receive chunks 122 from device 142. In some examples, device 152, based on the analysis of traffic data 312, may determine whether to request chunks 122 from device 142, or to receive chunks 122 from module 230.

In an example, device 152 may send chunks 122 stored in memory 154 to more than one device. Module 230 may analyze traffic data 312 to determine how many devices are receiving chunks 122 from device 152. Module 230 may be further configured to set a limit on the number of devices that may receive chunks from device 152. For example, module 230 may set a limit of four devices which may receive chunks 122 from device 152. If traffic data 312 indicates that device 152 is sending chunks to four devices, module 230 may generate alert 320 to indicate that the maximum amount of devices receiving chunks 122 from device 152 has been reached. Module 230 may send alert 320 to device 152. Device 152 may receive alert 320 and in response, may determine whether to allow additional devices to establish communication channel 270 with device 152, and/or to receive chunks 122 from device 152. In some examples, device 152 may be configured to execute instruction 216, stored in memory 152, to determine whether to allow additional devices to establish communication channel 270 with device 152, and/or to receive chunks 122 from device 152.

Display of content 124 on devices 142, 152 may be facilitated by an interface 318. In some examples, interface 318 may be an output of an application such as a white-labeled video player application. In some examples, interface 318 may be an output of a web browser application. In examples where interface 318 may be an application of a cellular phone, instruction 216 may be a library which may be embedded in a cellular phone application. Interface 318 may be further effective to display content 124 and to display traffic data 312. In the example, interface 318 may include a retrieval distribution indicator 310, which may be a graphical indicator effective to indicate, such as by color or shading, whether each chunk 122 is received from content delivery domain 110, or from a device through communication channel 270. In some examples, retrieval distribution indicator 310 may further indicate a device from where each chunk 122 is received. For example, if device 152 established communication channel 270 with a first device and with a second device, retrieval distribution indicator 310 may indicate whether a chunk is received from the first device or the second device. In the example, retrieval distribution indicator 310 may indicate that chunk 122 b may be received from the first device (labeled as “1”). In some examples, retrieval distribution indicator may be effective to indicate how many times a respective chunk has been distributed to another device. For example, if chunk 122 b has been distributed to two devices, retrieval distribution indicator 310 may show a number “2”.

Among other possible benefits, a system implemented in accordance with the disclosure may benefit content providers, content delivery networks, and users who wish to view a live broadcast or live streaming content. The system may benefit content providers by reducing a need to purchase huge amounts of resources from content delivery networks. The system may also benefit content providers by improving a distribution efficiency of content and may benefit content delivery networks by alleviating the load on the resources of content delivery networks. A reduced load on the resources of content delivery networks may reduce a risk of damaging the resources, which may be costly to fix. The system may also benefit users who which to view a live broadcast by providing additional sources, such as a peer-to-peer network, of the content. Users who are viewing a live event through a network such as the Internet, may download different parts of the content from both the content delivery network and other devices that are showing the same content. The additional source of content during a live event may allow the user to view the content without interruptions.

FIG. 4 illustrates a flow diagram for an example process for implementing hybrid content delivery system, arranged in accordance with at least some embodiments presented herein. The process in FIG. 4 could be implemented using, for example, system 100 discussed above. An example process may include one or more operations, actions, or functions as illustrated by one or more of blocks S2, S4, S6, S8, and/or S10. Although illustrated as discrete blocks, various blocks may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation.

Processing may begin at block S2, “Receive a first request from a first device”. At block S2, a processor may receive a first request from a first device. The first request may be a request for content. In some examples, the content may be a video.

Processing may continue from block S2 to block S4, “Send at least a first chunk of content data to the first device”. At block S4, the processor may sent at least a first chunk of content data to the first device. The content data may be associated with the content.
